Isochronous channel having a linked list of buffers

A computer system, comprising:

• an isochronous channel having a linked list of buffers configured to receive isochronous data transmitted within said computer system;
• a sender client associated with said isochronous channel and configured to transmit said isochronous data, said sender client being a software driver routine associated with a sender node of said computer system;
• and
• a listener client associated with said isochronous channel and configured to receive said isochronous data, said listener client being a software driver routine associated with a listener node of said computer system;
• and
• DMA hardware configured to transfer isochronous data into a buffer of the linked list of buffers by initiating a DMA transfer,
• wherein said sender client has an associated channel identifier that is provided to said listener client.

A method comprising:

• establishing an isochronous channel within a computer system to receive isochronous data transmitted from a first device driver to a second device driver;
• by the first device driver, adding a sender client configured to transmit the isochronous data to the isochronous channel and providing the sender client with a channel identifier;
• passing a reference to the channel identifier from the first device driver to the second device driver;
• and
• by the second device driver, adding a listener client to the isochronous channel by providing the listener client with the channel identifier.

A sequence of computer-readable instructions embodied on a computer-readable storage medium comprising:

• instructions arranged to cause a processor to establish an isochronous channel within a computer system to receive isochronous data transmitted from a first device driver to a second device driver;
• instructions arranged to cause the first device driver to add a sender client configured to transmit the isochronous data to the isochronous channel and provide the sender client with a channel identifier;
• instructions arranged to cause the first device driver to pass a reference to the channel identifier to the second device driver;
• and
• instructions arranged to cause the second device driver to add a listener client to the isochronous channel by providing the listener client with the channel identifier.

A computer system, comprising:

• an isochronous channel configured to receive isochronous data transmitted within the computer system from a first device driver to a second device driver;
• a first device driver associated with a first device, the first device driver configured to add a sender client configured to transmit the isochronous data to the isochronous channel and provide the sender client with a channel identifier, the first device driver further configured to pass a reference to the channel identifier to the second device driver;
• and
• a second device driver associated with a second device, the second device driver configured to add a listener client to the isochronous channel by providing the listener client with the channel identifier.
